PURPOSE:To increase the amount of electrolyte stored so as to extend the liquid supply frequency by providing an elastic conductor impregnated with electrolyte in a space surrounded by frame-like sealing members attached to the peripheries of the end surfaces of stacked unit blocks thereby forming a liquid storage chamber, and connecting it to liquid storage grooves corresponding to unit cells through a liquid supply path. CONSTITUTION:Elastic conductive members 9 attached to flat surfaces surrounded by frame-like fluorine-system rubber sealing members 8 spliced onto the top and the bottom of a unit block 1, are impregnated with phosphoric-acid electrolyte. The frame- like sealing member 8 is attached to the flat surface of a half plate 5' located at the bottom of an upper block 1 so as to form a liquid storage chamber 10, surrounded by the frame-like sealing members 8, between the facing half plates 5' and 5' of adjacent blocks 1. The liquid storage chamber 10 formed between the blocks 1, is connected to liquid storage grooves corresponding to unit cells through a liquid supply path which penetrates gas-separating plates 5' and 5. Owing to such constitution as above, arrangement of the stacked members is facilitated, and a deteriorated cell can be replaced for each block. Besides, the liquid supply frequency is extended 4-5 times as compared to one having only liquid storage grooves. |
